The chimneyl structure, illustrated' inthe dinv'rings,and: consistingessentially of the` fireplace l with its i'irebox 2, ornamentalfad..ings :3, and shelf 4, and the chimney flue 5f:

ney fine. The vfirebox. 2 is .usually provided4 Withanaarched firebrick'backing 7.Which exe tends from the base ofthe firebox in curved805 form upivardly'andforwardly to the .chim-- ney throat 8I formingbehiIid-the upperpoi'-P tion of this backing; a shelf or ledge 195 for;di rectiiig the return draft passing downwardly at the rear, side ofthechimney liuc. At. the lateral sides oftliefirebox andat the. upper endsof the side Walls theieof,are providedsupporting ledges 10` which are`at theisame elevation as the upper end .ofI the firelorick 'facing 7, asshown in Figs, 1' and` 2. vMy

chimney throat liner,v designated 11, v isy posi-l tioned Within thethroat portion lof'theichimico@ g Y may be laid against and constructedupon the Y VMy chimney throat liner, in its preferred form ofconstruction, is made of terra cotta and molded as a single and completeunit in the form shown. This form is a hollow truncated pyramid having aflat and vertical rear wall 1l, a front wall llb which is in the shapeof a trapezoid and inclined backwardly and upwardly, and lateral sidewalls, alsov trape# zoidal in shape, inclined inwardly and` upwardly andjoining at its edges the lateral edges of the rear and front'walls, asvindi- V Y cated by 11C. The inner faces of the walls forming this linerconnect the ireboX, at the upper portion thereof, in smoothV lines andin unobstructed surfaces, with the inner faces of the flue liner 6 ofthe chimney flue 5.- The portion of the fireplace behind the facing 3 isusually built up of brick andthe forward wall of the chimney throatformed as steps in warious irregular form forming pockets and materiallyobstructing the passage of the gases of combustion and smoke to thechimney flue,'often causing the same to pass downwardlyinto the room. ByVemploying my flueliner, thebrick andlmortar forming the front andlateral sides of the throat `portion liner as a form, thus making asolid, rigid and compact structure, as well as facilitating `theconstruction of the chimney throat. The

front wall of the liner directs the heat away from the brick and mortarand reduces to a minimum the destructive action on the same 4pendedclaims.

the chimney, or upper portion of the fireplace or mantel, is eliminated.The same is true also of the'other walls forming the chimney throat.

Though l have shown and described a particular construction,combination, and arrangement ofparts and portions, l do not wish to' belimited to this particular con-V structiom'combination and arrangementbut desire tolinclude inthe scope of my invention the construction,combination and arrangement substantially as set forth in the apvHavingthus j l claim as new andV desire to secure by Letters Patent is: A" Y Yl. A molded chimney throat liner open at its'lower and its upper ends,the rear wall being flat and substantially vertical, the front wallbeing inclined upwardly and backward described my invention, what lyfrom its lower to its upper end, and its side walls being upwardlyconvergingv with vrespect to each other and joined to the rear and frontwalls, Vall forming a free unobstructed upwardly converging andgradually reducing passage from its lower to its upper end, saidlinerbeing adapted to be telescoped over and within other liners forAstacking and economically storing the same, the inner surfaces of allwalls of one liner, when stacked over another-liner", engaging the outerwalls of the latter. Y

' 2. A chimney throat liner having a large rectangular opening at. itslower end and a smaller correspondingly shaped opening at itsfupper end,one wall of said liner being Asubstantially vertical and t-he otherwalls being inclined upwardly and inwardly from rthe lower to theupperends of the liner, all

forming va free unobstructed upwardly converging and gradually reducingpassage from its lowerto its upper end, the lower andupper supportingedges of the walls being the width of the thickness of the walls, thelower edges supporting the liner in the chimney throat and .the upperedges being adapted directly tosupport a flue liner, saidliner beingadapted to be telescoped over and within other liners for stacking'andeconomically storing Vthe same, the inner surfaces of all walls of oneliner, whenstacked'over another liner, engagingv the outer walls of thelatter.

` 3. In a chimney structure, a large irebox portion, a `chimney flueliner positioned and extending above the same,-and a chimney throatliner contracted gradually from its lower to its upper end and havingplain walls from its lower to its upper end, the termination of thewalls at the eXtreme upper and lower ends being of the same thickness asintermediate portions, forming narrow supporting edges and upwardlyconverging smooth lines at the inner and outer sides of the walls, thelower end of said flue liner resting upon and being lsupported by thenarrow edges of the upper end of the throat liner.

e. A. molded chimney throat liner shaped as a-hollow truncated pyramidwholly open at its upper and lower ends, said liner being adapted to betelescoped over and within other liners for stacking and economicallystoring the same, the inner surfaces of all walls of one liner, whenstacked over another liner, engaging the outer walls of the latter.

In testimony whereof, I have hereunto set my hand at Los Angeles,California, this 16th day of November, 1926. t,
